Serial No. 585,286.

To all whom fit may concern:

Be it known that I, ALLEN DAvIs Gosn'r'r, a citizenof the United States, residing at Burleson, in the county of Johnson, State of Texas, have invented certain new and useful Improvements in` lVheelwright-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in wheelwright machines and the leading object in view is to provide a machine adapted for bolting the tires to the Wheels, having a slidably mounted Wrench shaft and improved means for sliding the wrench shaft.

Another object of the invention is the provision of a bolting machine for operating on vehicle wheels and having a slidable wrench holding shaft, with a treadle operating device whereby the wrench holding shaft can be forced against a felly, while the wrench shaft is rotated.

With the above and other objects in view the invention consists in certain constructions, combinations and arrangements of parts, clearly described in the following specification and clearly illustrated in the accompanying drawings, in which Figure 1 is a side elevation with the treadle broken away. Fig. 2 is a plan view thereof. Fig. 3 is a central longitudinal sectional view. Fig. 4 is a transverse sectional view taken on the line 4 4 of Fig. 2. Fig. 5 is a sectional view on the line 5 5 of Fig. 3.

Referring to the accompanying drawings illustrating the preferred embodiment of the invention 5 denotes a table which is mounted on standards 6 and an adjustable standard 7. The adjustable standards 7 are formed with. Socketed upper ends to receive the depending legs of the table 5, and the socketed upper ends are adjustably secured by means of wing nuts 8. The table 5 is provided with a pivot 9 secured at its lower end thereto on which a wheel 10 can be rotatably mounted. A block 11 is longitudinally disposed on the table 5 and said block is provided with a longitudinally eX- tending slot 12. On the slotted end of the block 11 a metallic plate 13 is mounted. The plate 13 is provided with a post 14 which carries a sleeve bearing 15 on its upper end. A shaft 16 is disposed in the longitudinallslot of the block 11 and said shaft carries a gear wheel 17 the upper end of which projects through a transverse slot 18 in the block 11. A second plate 19 is mounted on the block 11 over the slot 12 thereof, and one end of said plate is upturned to form an abutment 20, which is integrally connected with a second abutment or backing 21 which terminates in an extension 22, said extension being suitably bolted to the block 11. The plate 19 is provided with an upstanding post 23 which carries on its upper end a sleeve bearing 25. A shaft 26 extends through the sleeve bearings 15 and 25 and carries a gear wheel 27 which meshes with the gear wheel 17 of the shaft 16. rlhe gear wheel 27 is covered by a yoke or strap 28 which has its terminals 75 fastened to the table 5. The shaft 26 is formed with spaced circular shoulders or bearings 29 between which the fork 30 of the adjusting arm 31 is received. The adjusting arm 3l extends vertically downward 80 through the slot 12 of the block 11 and is provided with a horizontal extension 32 which slides in bearings 33 depending from the under side of the table 5. The horizontal extension 32 is provided with a fixed 85 shoulder 34 and a spring 35 is mounted on said extension so as to bear at one end against the shoulder 31 and at the otheil end againstthe bearing 33 adjacent thereto. The horizontal extension 32 is provided with 90 a hook terminal 36 which receives the upper end of the pulling chain 37. The chain 37 operates over a sprocket wheel 38 which is mounted between the sides of the U-shaped bearing 39 depending from the lower side 95 of the table 5. The lower end of the chain 37 is connected to a treadle L10 which is suitably pivoted to a block 4.1. The shaft 16 is provided with a crank 16a whereby the same may be rotated and motion imparted 199 to the shaft 26, and said shaft 26 is provided with a suitable wrench for turning nuts and removing bolts.

Vhen the shaft 16 is rotated by manipulating the crank 16a motion will be imparted 105 from the gear 17 to the gear 27 and the shaft 26 will be rotated. In order to effect a longitudinal movement of the shaft 26 and the wrench pressure is applied upon the t-readle 40 so as to move the chain 37 110 over the sprocket wheel 38 and force the shaft along its bearings 15 and 25 by means of the operating arm 31. The spring 35 normally holds the chuck 42 away from the abutment 20 so that when pressure is released from the treadle 40 the wrench will be drawn away from the abutment and the nut carried thereby will be moved away from the felly.

What is claimed is- The combination in a device such as de scribed, of a table, blocks secured to the upper side thereof and arranged in spaced parallel relation to each other, a plate connecting the upper edges of the said blocks, the said plate being bent upwardly near one end to produce an abutment for the tire of a wheel, a pivot movable through a slot formed in said plate for engagement with the hub of a wheel, a shaft journaled be tween the blocks, an operating crank attached to one end of the shaft, a pinion leyed to the opposite end of the shaft, bear-v ings formed upon the upper side of the plate, a shaft longitudinally movable in these said bearings, a pinion slidably keyed to the longitudinally movable shaft and engaging the first mentioned pinion and held in engagement therewith by the bearings, a protector secured to the plate and surrounding the pinions, a nutengaging head upon one end of the movable shaft, spaced collars carried by the opposite end of the movable shaft, a rod slidable belowsaid table, an arm extending vertically there from through a slot formed in the table and engaging the collars, a treadle pivoted below the table, a chain connecting the treadle with the movable rod, a sprocket wheel engaging the chain and a spring located upon the movable rod, substantially as and for the purposes set forth.

In testimony whereof, I affix my signature, in presence of two witnesses.
